SPECIFICATION forming part of Letters Patent No. 367,358, dated August 2, 1887.

I Application filed August 12, 1886. Serial No. 2l0,706. (No model.)

To all whom it may concern:

Be it known that we, JosE'rH W. BRAINARD and ALANSON D. SWAN, citizens of the United States, residing at Kent, in the county of Port- 5 age and State of Ohio, haveinvented a new and useful Improvement in Window-Blinds, of which the following is aspecification.

In the drawings forming a part of this specification, Figure 1 represents a window-blind with parts broken away at the connection of a slat with the stiles; and Fig. 2 is'a cross section ofa slat-tenon, showing the inner side of a part of a stile.

The slats a are formed or provided at their ends with tenons consisting of thin metallic tubes 0. These tubes, being formed of thin sheet metal, may be driven into the ends of the slats without splitting the latter. The stiles b are formed with cylindrical holes to receive short rubber tubes s, in which the slattenons c are tightly inserted in order that the compression ofthe rubber tube on the tenon 0 may hold the slats in any position to which they may be turned. Rubber tubes 8 should 2 be either glued in the holes in which they are placed in the stiles or tightly fitted therein so as not to turn with the tenons 0. They may be used in connection with any ordinary slattenon; but we prefer metallic tenons to wooden 5o ones in order to lessen the wear from friction.

The series of slats a is operated by rod (7, hinged to each slat in the ordinary way, and therefore it is not necessary that rubber tubes 0 should be applied to both ends of .the slats 5 nor to all the slats'for the purpose of holding them in any position to which they may be turned; but it is desirable to apply the rubturned by any ordinary means.

In Fig. 1 rod d is shown as lifted and the slats a thereby closed. The rod is held in that position by sliding stop it. lVe prefer to form it with outwardly-bent ends, the end under the rod projecting far enough to prevent rod cl from being forced down to open the slats. The other end of stop a may be grasped to slide it back ward and forward. In the drawings it is shown as connected by staples o to a plate, 1;, attached to the lower part of the window-frame, but the plate may be dispensed with and the stop directly connected with the window-frame.

WVe claim as our inventi0n- A window-blind slat formed with a tenon, in combination with a stile formed with a hole provided with a rubber tube to receive said tenon, substantially as described.
